As we usually (unfortunately not always though) do not use abbreviations.
Tx may be standard abbreviation, but we already have e.g.
TransmitChecksumOffload=. So, let's use Transmit instead of Tx.
Follow-up for ef4a91a7e8.
Let's tighten the logic behind path_extract_filename() a bit: first of
all, refuse all cases of invalid paths with -EINVAL. More importantly
though return a recognizable error when a valid path is specified that
does not contain any filename. Specifically, "/" will now result in
-EADDRNOTAVAIL.
This changes API, but none of the existing callers care about the return
value, hence the change should be fine.
Otherwise, the list becomes dirty when an entry is freed.
This also remove the entry from the hashmap only when its name is set.
The name should be always set, so that does not change anything. But
just for safety.
This should not change anything. As hashmap_remove() is called before
hashmap_ensure_put(). So, even if hashmap_ensure_put() fails, a wrong
entry will not removed from the hashmap by udev_list_entry_free().
But anyway, just for safety.
When epoll_wait() returns number equivalent to the buffer size, there
may exist remaining events which may have higher priority. To make priority
sorting correctly, let's retrieve all events.
Let's make these functions a little more generic so we can have
them work on more than one GUID. More specifically, this allows
using them with the global guid which will be used a bit more to
extend the secure boot support.
Instead of using -nostdinc, we use -nostdlib. This is necessary
to allow moving to C99 as efibind.h includes stdint.h when C99
is enabled. It isn't necessarily problematic to use some standard
library headers as long as they don't contain functions defined in
libc or another system library (or in other words, header only
headers are fine to use in sd-boot).
CLI tools may be used in a script. E.g., a script for monitoring a
service may use `systemctl`. Previously, if the kernel command line has
e.g. systemd.log-level=debug, then systemctl in the script produces
debugging logs when the script is invoked by a .service unit, but does
not when the script is running in a terminal. Then,

In the previous commit, $SYSTEMD_EXEC_PID= is introduced. Then, we can
now detect whether a command is directly invoked by systemd or through
a script. Let's skip reading the kernel command line when a command is
invoked through a script.
This effectively reverts 41d1f469cf.
Before this, e.g., `networkctl reload` invoked by `systemctl reload systemd-networkd.service`
does not produce debugging logs even if systemd.log-level=debug is set. This fixes
the issue.
I think this formatting was originally used because it simplified
adding new options to the help messages. However, these days, most
tools their help message end with "\nSee the %s for details.\n" so
the final line almost never has to be edited which eliminates the
benefit of the custom formatting used for printf() help messages.
Let's make things more consistent and use the same formatting for
printf() help messages that we use everywhere else.

GetMulticastHosts() returns an array of hostnames/addresses discovered via
LLMNR or Multicast DNS. It does not trigger any discovery on its own.
Instead, it simply returns whatever is already in resolved's cache.
